I have a 2002 grand prix with the 3.1 sfi. I have had nothing but problems with this car lately. My tach does not work & my tcc light is on. My check engine light is also on. I get code PO336 which is the crank sensor. I replaced both crank sensor but the PO336 code keeps coming back. Does my tcc or tach have anything to do with this code? A friend of mine said I could have a pin hole in a vacuum line someplace. Anybody have an idea whats wrong with this car? Im about ready to set fire to it & walk away. Thanks for your time.

dont burn it just give it to me
your tach could have somthing to do with it since your tach is ran off the CKP
do you know why your tach stoped working or whats wrong with it?
and when you scan it does your scanner read rpms? if so then check to see if it read rpm when the motors running. if that works and it reads fine then you know the sensor is fine and then that its more the likely just the tach tripping the code
